Allochthones along the West Section of the North Qilian Orogenic Belt

Allochthones are well developed along the west section of the North Qilian orogenic belt. These allochthones can be divided into two types; nappe and slide nappe. In this paper,the material composition, structural style, kinematics and dynamics of these allochthones have been discussed. It is pointed out that the study of the allochthone has great significanae for the correct reconstruction of paleogeographic and paleotectonic frameworks of orogenic belt and the study of dynamic transposition in the orogenic process of the orogenic belt.
